Continuous Air Quality Monitoring Data (LEADS):

Providing access to Indiana's continuous air quality monitoring network, IDEM's Continuous Air Quality Monitoring Data maps offer access to near real-time data from air monitors across Indiana. Approximately 65 percent of Indiana's air monitoring network is now available via this system.

This is an interactive map with the statewide distribution of the fixed station water monitoring sites. It provides the station name, location description, photos where available of upstream and downstream, and a list of parameters sampled.

This interactive map provides a display of the impaired waters along with additional information associated with the listings, such as the development status of TMDLs and the establishment of watershed management plans (WMPs). Additional guidance on the use of the e303d is available.

Interactive map to view watershed management, land use planning, and water quality analysis. This map focuses specifically on Indiana’s water quality and how it is affected by land use change. Additional guidance on the use of IWQA is available.

This is an interactive map that allows land owners to volunteer their property to be a mitigation site for other projects in their area. Additional information is available on the IDEM Wetlands, Lakes, and Streams Regulation website.
